Nobody denied that there was mercury (in thimerosal) in vaccines. That was not being hidden. The FDA started to phase its use out in 1999. You mention that phenol is used in mouthwash, so you follow up with "inject that mouthwash into my arm". Phenol is used as ingredient in mouthwash, but nobody injects mouthwash (which contains several different ingredients) in your arm. Bad argument. These ingredients were used because people died from bacterial infections from multi-dose vaccines (where the same vial is used for several people). I think it makes more sense to base your arguments on facts, not "they're injecting mouthwash into my arm. No thanks".
